Celebs and activists tweet in support of #NationalWalkoutDay

On Wednesday morning, students all across the country walked out of their classes to protest gun violence.

The protest was organized to demand Congress to enact stricter gun control measures, including banning assault weapons, requiring universal background checks before gun sales, and passing a gun violence restraining order law that would allow courts to disarm people who display warning signs of violent behavior, according to CNN.

Students planned to walk out for 17 minutes, in honor of each of the 17 people who died during the shooting at Marjory Stoneman Douglas High School in Parkland, Florida exactly one month ago.

Marking the occasion, the student activists from Marjory Stoneman Douglas shared their support for the walkout on Twitter.

You have such a STRONG voice. Keep using it. Keep marching. Keep walking out. Cause some good trouble. #NationalSchoolWalkout

One month ago today, we were all changed. #IWillMarch so no child has to lose their innocence like we did. #IWillMarch so my children don’t have to experience what we all went through.#IWillMarch because my generation—the mass shooting generation—has had enough.

so proud of my high school students – for walking out today – to every kid who found the strength to use they voices in spite of threats of detention – thank u all – #ParklandStrong#HELLnoNRA#NeverAgainIsNow

The young people of this generation give me so much hope. Are u listening @GOP? Time for gun laws to change. And for you 2A-ers, relax, no one is saying you cant own a gun, your right to ‘bear arms shall not be infringed’. Just looking for common sense reform! #NationalWalkoutDayhttps://t.co/jB7NCb0MJj

On the one-month anniversary of the Parkland school shooting, students are walking out in protest of Congress’ failure to act on gun violence. Let’s support them, and the March to Washington DC in ten days👊🏻 #MarchForOurLives

To all the students walking out today to honor of 17 killed in Parkland & demanding action against gun violence: We will follow your lead and protest with our voices, our bodies and our votes. This is just the beginning. See you in Washington on the 24th. #NationalWalkoutDay

Seeing these kids around the country walk out of their schools and make their voices heard for #NationalWalkoutDay gives me hope for the future. Know that we stand with you and we walk with you. #NeverAgain.

So unbelievably proud of these students. So blown away by their unstoppable energy and their devotion to hold our legislators accountable. They are not going away, but those officials who do nothing to reform gun laws, most certainly will be. #walkout#ParklandStronghttps://t.co/928ee1lBJC

The spirit of #NationalWalkoutDay is familiar: 55 years ago, thousands of children skipped school to protest segregation in the streets of Birmingham—a moment that forever changed the Civil Rights Movement.

Students will chart the course of our nation’s future. If adults try to ignore your words, rest assured that we will hear your footsteps. To all those walking out today, thank you. #NationalSchoolWalkout#NeverAgain
